These Is What Sandwich Panels Are All About |
|
The Sandwich Panels are used mostly in huge industries and companies for their internal fixtures. These panels basically consist of two outer layers that are interconnected by another layer called the core layer. The outer layer can be sheets, slabs of wood, metal or paper. The inner material is made out of plywood, plastic sheeting or the honeycomb structure. Many of the panels of this category are also formed of inner cores made out of plastics. Placing the plastic sheet between the heated molds forms it. This results into a definite cellular structure. The description of how this instrument works requires some pre-requisites, i.e. the person with little engineering experience can understand it well. The Sandwich Panel consists of I-beam, where its flanges are bonded to the web so as to create a structural member. The strength that is required between the two edges of the flanges is acquired by keeping the two flanges in compression and tension. A sandwich panel is very similar to the I-beam. The things that correlate between them are the skin of the panel and the core of the panel. The skin correlates to the flanges of the I-beam where as the core relates to the I-beam Web. The panel bears a bending strength on all the directions of the plane, the X-Y plane, and Z-X plane, except the Y-Z plane. The core has the major functionality of the sandwich panel, i.e. it is responsible for holding the skins together and relative to each other. This helps in avoiding the buckle, snap, deformation or brokerage. The core of the sandwich panel experiences mainly the shear stress. The stiffness of the material can be known by examining the shear properties. The cores that are more flexible and bend easily are known to have low shear modulus. To avoid this, another material can be bonded to the surface and creating a skin with higher tensile strength. This leads to the construction of Composite sandwich panels. Thus the sandwich panels can be used where strong, stiff, lightweight panels are required. They support the properties like the rigidity, strength, compressibility, and flexibility; also maintain the shape, size, thickness, and weight. The main motive is to build or construct a panel that is light weighted. They can be formed by using thin plastic sheets as the as the core area. They should have broad bonding areas at their free ends and also to bond with outer areas. The projections can be made out of different shapes, heights, spacing, tilts etc. These different projections help to produce different characteristics in the panel being made. As many of the characteristics can be well known at the beginning, it can be designed on the computer itself. With use of this many useful applications such as the airplane wings and the thermal boards can be designed. Thus the panels are widely used in many industrial and commercial applications of the day-to-day life. Thus, each panel possessing some different characteristics suitable for that particular environment.
